Had my X3 2.0d xdrive done in Bodmin Cornwall. What differences 42/45 mpg around the lanes of Cornwall, and on a run to Northampton I do a lot 50 mpg. The acceleration is fantastic. Very pleased.

Dynoed 3 cars that were made in quantum, 2 of them had less than 20 000 km when chipped, so not single one of the cars did succeed in reaching powers that were claimed on quantums website, emailed about this straight to UK HQ, and the answer was bad, basically, if I can feel that car pulls faster, it's enough for them. Then dragy measured other cars with same setup, tho different stage 1 tuner... well.. it was like hes on a jet, and I'm running.

Tho our fault that we dynoed later than 30days money back guarantee, but if youre missing 60 chalimed hp, and about the same on torque.. well, never use quantum. Read google, most of the reviews are fake, ask anyone you know in motorsport or in car community - never heard of quantum.

I went for the cheap, well, my fault, quality doesn't come with that price.
AVOID! Customer service is bad in HQ and Dealer end.

Edit.. Quantum just gave a reply.. Same automatic reply like on email, even that I told that we took dragy acceleration times and well guys.. You know how to vote. Funny thing also, the guy at quantum didn't do any data logging before and after. Of course cause first 30 days you have the placebo effect that you got power. Cause 50nm is a lot. Lol. Use apr or eurodyne instead

Great friendly service and it’s made a huge positive difference to the performance and efficiency of the camper van.

We received great service from Snow's Garage in Stoke on Trent. We were a little worried at first but all our fears were put to one side once we spoke to the owner and he was very professional and helpful

Big thanks to patrick for tunning my new purchase (golf r ) great gains as per usual,as with all my cars I've had , wouldn't use anyone else other than kev & Patrick . Cheers guys , see you soon for the next one 😁😁😁👍👍👍

Very good service, and can feel the gains even in a little Clio, very good customer service aswell, and kept up to date on everything that was going on, recommend everyone to use quantum tuning remaps

Still to have a proper shot of the car since the re-map but so far so good!

Excellent service, very friendly chap, from order online to comeplete was just 4 hours, very quick! happy with the results too!

Had my s3 done by jw in colraine top class job and car drives so much better can stay in 6th gear a lot longer and car just pulls better. Money well spent.

Apart from the better Power delivery.
It’s a lot smoother. 100% would recommend

I availed of Quantum tuning via an authorized agent and there are no words to justify the quality of these guys just 110% from start to finish and the difference in my car is night and day when I get a new car I'll be getting that tuned as well and ever car from here on out, I'll even be suggesting that friends get it done, it's top quality and the guys are friendly and there is no such thing as a stupid question with them 👌 🌟🌟🌟🌟🌟

Just want to say a huge "THANK YOU" to James at Crackley Garage, Kenilworth for bringing my BMW 428i back to life!

Just had a Stage 1 remap and the response and lack of turbo lag is amazing, literally pulls in every gear, especially 3rd and 4th. Fuel consumption seems a lot better.

Would highly recommend a remap from this place, trustworthy and very professional.

Also huge thanks to James for offering the use of his office whilst I was on calls with work, great service and one very very happy customer here!

Fantastic excellent well pleased thank you Rob Lawton for a job well done 👍

Amazing leap in performance especially mid range torque improvement. Would definitely recommend Quantum Tuning Romford. Worth every penny.

Good services. Engine work much better now!
Only I'm disappointed because haven't chart of power and torque before and after remap.
That's I give ony 4*

First class service. Highly recommend

Excellent service, real professionals

Car Club Ltd, Lyne, Chertsey
